FUMIGATING DEVICE Fil ed OCT.. 26, 1929 Patented Aug. 18, 1931 UNITEDs'rares Artnr' ori-ice EDWARD THORNDIKE LADD, F LEVISTON, NEW YORK,ASSIGNOR TO ISCO CHEMICAL COMEANY, INC., OF NIAGARA FALLS, NEV ORK, ACORPORATION OF NEW YORK FUMIGATING DEVICE Application led October 26,1929. VSerial No. 402,613.

My invention relates in general to fumi gating devices, and moreparticularly to a hermetically sealed chest within which garments may beplaced for treatment or storage.

he principal object of my invention has been to provide a device sodesigned that f when the cover thereof is closed, a definite charge ofliquid or gas will be released within it.

Another object has been to provide a fumigating unit which may be easilyremoved from the chest forrenewal.

Moreover, my fumigating unit is so de? Fig. 2 is a sectional viewthereof, taken on' line 2-2 of Fig. 1.

Fig. 3 is a fragmentary, perspective view of my fumigating chest.

Fig. 4 is a fragmentary, vertical, sectional view, taken through thewell for the fumigating unit. Y i

Fig. 5 is an enlarged fragmentary, seetional view showing suitable meansfor hermetically sealingr the cover.

My device comprises a chest 10, of wood or other suitable material,having a hinged cover 11. Suitable means such as a strip 12 of resilientmetallicl or rubber material may be secured either to the underco-acting edge of the cover or the upper co-acting edge of 45 the chestso as to hermetically seal the joint between the cover and the chestwhen the cover is lowered.

In one corner of the chest there is providn ed a well 15 which ispreferably formed of a blockof wood 16 into which the well is drilled orbored. The well is provided with a plurality of lateral or upwardlyinclined apertures 17 in oneV or both of the exposed surfaces. The wellis of such a size and depth as to receive the fumigating unit 20.

The fumigating unit comprises a casingl 21 formed of suitable metal andprovided at its upper edge with screw-threads for the screw-threadedreception of a cap 22. The cap 22 slidably carries a plunger 23, havinga foot `24@ secured at its inner end, and an operating button 25 securedat its outer end. The bottom wall 26 of the unit is provided with acentral aperture 27 through which the fumigant escapes. A screen 28 ispreferably arranged in the bottom of the unit whereby particles of thebroken glass ampoule 29, used with my device, may be retained within thecasing 21. Any suitable fumigant may be used in the ampoule, and dependssomewhat upon the treatment to be given the contents of the chest, but Ipreferably use chlorpi'crin The parts of the fumigating unit are soproportioned in relation to the depth of the well 15 that the operatingbutton 25 will project upwardly to a position where the cover 11 willcanse it to be depressed before such cover has reached its closed posi.-

tion, whereby the device is operated.

Obviously, after the garments to be treat- Y ed have been placed withinthe chest, and an ampoule 29 containing the suitable liquid or gas hasbeen placed within the unit, the cap 22 of the unit is screwed down andthe unit is placed within the well 15. The cover Y 11 of the chest isnow closed with a positive pressure which causes the foot 24 carried bythe rod 23 to be forced into the upper end of the ampoule, thus breakingthe same. The gas produced by vaporization of the liquid will passthrough the opening 27 of the casing 21 and out through the openings 17,charging the chest and its contents with vapors of the agent used.

. 1f the garments so treated are to be stored, the chest is, of course,kept closed, whereby the fumigating vapors will be retained with` in thechest and the garments contained therein. If, however, the garments areto be treated to disinfect or moth-proof them, they are allowed toremain Within the chest for a suitable length of time after which theyare removed from the chest. The fumigating unit is removed from the Welland the cap 22 is unscrewed, whereupon the broken fragments of glass maybe removed by dumping them out, and Without their coming in contact withthe hands. A new ampoule may 'be placed Within the body, the cap 22screwed thereon, Vand theunit placed Within'the Well.

The device is then ready for further use.

lhile I have shown my device as applied to the body of the chest 10i, it.is obvious-that it may be carried in any suitable manner by the cover,and the same advantages derived. This, andother modii'ications of thedetails herein shown and described may be made with out departing fromthe spirit of my invention or, the scope of the appended claimf, and ldo not, therefore, Wish to be limited to the exact embodiment hereinshown and described, the form shown being merely a preferred embodimentthereof.

`Having thus described my invention, What I claim is:

1. A fumigating device, comprising a chest, a cover for the chest, aumigating unit carried b v the chest, comprising a single-piece,hermetically sealed, brealzable container, and means engagea'ble withsaid container for breaking the same when the cover is moved to itsclosed position.

2. A tumigating device, comprising a chest, a cover for the chest, afumigating unit carn ried by the chest, comprising a casing having anoutlet opening, a screen disposed over the opening, a glass ampoulecontain-edwithin the casing and resting upon thescreen, a cap foi-thecasing, a slida'ble plunger carried by the Vcap having a foot forengagement With the ampoule, and a button carried at the upper end ofthe plunger for engagement 'with the cover of the chest w' ien the sameis moved to its closed position, whereby the amponle is broken.

In testimony whereof, have hereunto signed my name.

EDWARD THQRNDKE LADD.
